Well, that was an experience. I just wasted one hour playing a game about cows, err, I mean COWs, and I've barely managed to finish first 6 levels! Alright, jokes aside, this is a really great game!
I liked nearly every aspect of it! It is a very innovative puzzle game, with a complex yet understandable gameplay, that is well explained in simple but funny dialogues. The only issue I had with that game, is that the levels are a bit too hard, but that might be just me, perhaps I'm too stupid to play a game about cows. But then again, completing such hard levels, was very satisfying, so I guess it's okay.
This game, also has nice pixelart graphics, which remind me of old puzzle games from the 90's and 80's. They're simple yet readable and pleasant.
The only thing that sorta bothers me, is that there is only one music track. Now, it's not bad, but when you're playing a rather difficult puzzle game about cows for a long time, it really gets annoying.
Overall, this is really, one of the best entry on this jam, you did a great job making it!
